An industry change in protocol from OBD II to Controller Area Network (CAN) has begun. In order to perform diagnostics on a vehicle that uses the CAN interface; you will need the Tech 2 Flash and a CAN diagnostic interface module. The module connects between the Tech 2 Flashs diagnostic link cable and the OBD adapter. Once the module is connected, it can be used on all GM vehicle applications,even those vehicles using other platforms such as OBD I and OBD II.

Tech2 is the most cost-effective one, for it is with reasonable price and covering not only For GM vehicles, but also For SAAB,For OPEL,For SUZUKI,For ISUZU and as well as For Holden.
Besides, it is with authentic For GM software and support on-board diagnostics on all gm systems. If you want to use it to do For GM car programming, you should buy tis2000 software.
One disadvantage is that tech2 remains an basic or essential gm diagnostic tool for vehicles before 2010.

For GM MDI is used to serve vehicles with auxiliary CAN bus that cannot be served by tech2. Actually, thisCar Diagnostic Tool is working with vehicles after 2010 and covering newer models than that of Tech2.
Its highlights are with faster reprogramming (increased about 20-70%), serving exclusive new models, and more economical. This is a good investment for future vehicles models.

How to disable GM, SAAB DRL with Tech2

Many people want to disable the day running light for fuel economy or other reasons, me included. Here I have figured out a simple way to reset it completely on my 1999 GM and my daughters 2004 SAAB with GM Tech2 scanner from my friend. This takes about 5 minutes from start to finish and will completely disable your automatic headlights so they will never come on. But all of the lights will function correctly. They just would not be automatic anymore.
Tools you will need:
GM Tech2 scanner for GM and SAAB
32MB PCMCIA Card for Tech2
A SAAB car (Here take my daughters 2004 SAAB for example)
